CUTTING TURGH WITH QSCILLATING TIP,

Application filed February 27', 1924; fieriei No. 695,475.

To olZ whom. it may concern..-

Be itknown that l, Crnnnnon J. Connnnr,

1 n citizen of the United States, residing at Les, Angcles, inthe county of Los Angeles, State of Californie, have invented a new and useful Cutting" Torch with ()scillating Tip, of which the following is a specification.

Although my present invention is referred to as a cutting torch with an oscillating tip, a preferred embodiment of this invention may comprise means capable of of fecting the bodily oscillation of an entire torch in a plane not extending longitudinally of the slot cut thereby.

It is afiu'ther object of this invention to provide means comprising a torch whose body or tip is providedwvith means for oscillating the same in amanner favorable to the cutting of a slot having a predetermined diameter and a predetermined transverse sectional outline.

It is an object of this invention to provide means for mechanically oscillating a single cutting torch, or the tip thereof, preferably about a projected center, during the cutting of a slot by a rectilinear or other traversing. movement imparted 'in' any preferred manner either to said torch or to the article slotted thereby.

It is a further object of this invention toprovide means comprising a variable-throwdevice capable of use in maintaining or varying at will either the width or the shape of a slot out by asingle torch during a traversing movement of a metallic or other object relatively thereto.-'

Other objects of my invention will appear from the following description of an illus-' trative embodiment thereof, taken iuconnection with the appended claims and the accompanying drawings, in which- Fig. 1 is a diagrammatic elevational vice of an oscillating torch and operating means therefor, one suitable relative position of a plate to be slotted thereby being indicated by dash lines. i

Fig. 2 is enlarged detail section on line Q--2 of l.

Figs. 3, i and 5 are respectively diagrams illustrating the procedures suitable to the cutting, by means of my novel oscillating torch, of slots expanding downwardly (Fig. 3), or provided with an intermediate the body of e tdrch whose tip 3 is disposed in proximity to saidplate, and 20 being an electrical motor or other suitable source of power for imparting an oscillatory movement to said torch, or to the tip thereof, during a relative traversing movement (produced by any preferredmeans not shown) between said torch and said plate, to effect a desired slotting of the latter.

Although anypreferred means might be employed to effect an oscillation of the torch 2, or of its tip 3, by motion transmitted from a-source such as the motor 20, I disclose for this purpose an organization comprising a shaft rotated by said motor and carrying Worms 5, 5, respectively engaging Worm Wheels 6, 6', from. which motion may be transmitted in any suitable Way to either or both of the ends of the torch 2.

. In order to transform the rotary motion,

of the Worm wheels 6, 6 into suitable oscillatory motion, I may employ means such as the links 7, 7 resiixeotively pivoted at their outer ends, as by means of pins 8, 8, to

straps 9, 9, surrounding the respective ends oi. the torch ,2, the inner ends of the mentioned links'being in turnpivotally connected to the Worm Wheels 6, 6 by means of Wrist pins 10, 1t) mounted thereon.

In order to permit of a suitable adjustment or control of the relative oscillation imparted to the respective ends of a torch 2, I may employ, in connection with the parts referred to, any preferred type of variable-throw apparatus, my disclosed means for this purpose comprising threaded shafts 11, ll provided with squared ends 12, 12 and rotatably mounted between cooperating pairs of lugs or projections 13, 13 upon fiat faces of the Worm wheels 6, 6, the exterior threads of the respective shafts ll, 11 being adapted to engage corresponding interior threads upon blocks 14, M carrying the mentioned wrist pins 10, and retained between guides 15, 15 on said .worm wheels.

In order to maintain a suitable distanc between a tip 3 of a cutting torch and the worlr to be slotted thereby, I may employ means such as the guides 16, adapted to be engaged by interfitting means projecting from an oscillated torch, my disclosed means for this purpose comprising a pair of oppositely extending pins 17 upon the strap 9 by which motion is transmitted to one end of the torch 2.

it is believed that the general modeof operation of an oscillating torch of the general character referred to may be understood from the foregoing description; but attention is called not only to the possibility of varying the mentioned oscillatory movement within wide limits by suitable adjustment of the respective wrist pins 10, 10'

upon the worm ,wheels 6, 6, but also to the possibility oi varying the character of a slot formed by mere variation in the position or a consequent projected center of oscillation relatively to the surface of" a metallic or other body slotted. Assuming, for example, that the tip 3 is of the general character illustrated in Fig. 6, this tip being provided with, a plurality. of non-parallel passages 18 for the delivery of a combustible mixture to produce a heating client and with K a central passage- 19 for the delivery of an excess of a cutting gas, it will be obvious that, when the wrist pins 10, 10 are respectively positioned as disclosed in Fig. l, a comparatively wide slot having substantially parallel Walls may be formed in the plate 1; whereas, if the lower wrist pin 10 were carried to a position nearer the center of the worm wheel 6', the entire torch might be oscillated about a, projected center in the general manner illustrated in Figs. 3, 4 and and. the various results indicated in these respective figures might then be obtainable by a mere variation in the perpendicular distance between the tip '3 and the )late 1.

While the term oscillating is use in the above description to designate the transverse movements of the torch, it into be understood that in its broadest aspect the present invention embodies a torch having any form of transverse movement by which is produced a slot of greater width than that produced by a transversely stationary torch orby which is produced a slot having converging, or diverging, side walls; such transverse movement of the torch may be of a character in which one or both ends of the torch are oscillated simultaneously in the same, or opposite, directions, or in which the torch is bodily reciprocated while maintained substantially normal to the plane of the work,

it being further recognized that the term vibrate will properly define such movements which may be short and rapid relative to the longitudinal translation of the torch or work.

10.

In testimony whereof, I have hereunto set my hand at Los Angeles, California this 21st day of February, 1924.
